A Work in Progress
by Abe Usher
Information assurance is defined as "information operations that protect and defend information and information systems by ensuring their availability, integrity, authentication, confidentiality, and non-repudiation. This includes providing for restoration of information systems by incorporating protection, detection, and reaction capabilities.
I am presently working on creating a taxonomy of information assurance, based on the three aspects of:
These three aspects of Information Assurance (IA) were highlighted by John McCumber  as well as a team of West Point researchers  as a component of works that define an integrated approach to security.
Within the next 6 months, I would like to create a taxonomy that graphically depicts the relationships of these three aspects.
My intent is that this taxonomy could be used by the academic community, industry, and government in improving the precision of communication used in discussing information assurance/security topics.
I have searched the Internet widely for a taxonomy of IA, but I have not found anything that is sufficiently detailed for application with real world problems.
I am posting my initial results here in hopes that an open collaboration
process (much like the open source software movement) will yield a useful
tool for the security community to use in addressing information assurance
